The invention discloses a periodic loss time calculation method and system based on Leiyu fusion. The method comprises the following steps: carrying out data fusion on video image data and radar detection data to obtain absolute space-time information of all vehicles; on the basis of the phase and the passing lane corresponding to each stage and according to the absolute space-time information, the additional time headway of each vehicle corresponding to the starting sub-stage in each stage is obtained; superposing the additional time headway of each vehicle corresponding to the promoter stage to obtain promoter loss time; on the basis of the phase and the passing lane corresponding to each stage and according to the absolute space-time information, effective green light prolonging time utilized by the vehicle in the clearing sub-stage is obtained; according to the effective green light prolonging time utilized by the vehicle in the scene clearing sub-stage, obtaining scene clearing sub-stage loss time; stage loss time is obtained according to the promoter loss time and the field clearing loss time, and loss time of one cycle is obtained according to the stage loss time corresponding to each stage.
本申请公开一种基于雷视融合的周期性损失时间计算方法以及系统。方法包括：将视频图像数据与雷达探测数据进行数据融合，获得所有车辆的绝对时空信息；基于每个阶段对应的相位以及通行车道，并根据绝对时空信息，获取每个阶段中启动子阶段对应的每个车辆的附加车头时距；将启动子阶段对应的每个车辆的附加车头时距叠加，获得启动子损失时间；基于每个阶段对应的相位以及通行车道，并根据绝对时空信息，获取清场子阶段内被车辆利用的有效绿灯延长时间；根据清场子阶段内被车辆利用的有效绿灯延长时间，获得清场子损失时间；根据启动子损失时间与清场子损失时间，获得阶段损失时间，并根据每个阶段对应的阶段损失时间，获得一个周期的损失时间。
